Dey! Just pretend that you're Jimi Hendrix! haha, just kidding.
Essentially more fills are required. You may also want to think about getting another guitarist who can handle the lead as well as rhythm - you guys can then alternate. That way, you have more options as a singer and a band.
The reason why you have a band and not be a solo artiste is to have wider options available, from a musical POV. Some readjustments may be necessary.
Just my 0.2
